To all whom it may concern:

Be it known that I, ALBERT MANN, of Stroud, in the county of Gloucester, England, a subject of the King of Great Britain and Ireland, have invented certain new and useful Improvements in Covers and Bindings for Books, ofwhich the following is a specification.

This invention relates to covers and bindings for books and has more particular re lation to the covers and bindings of loose leaf books.

he invention comprises novel forms of covers, which however, are applicable generally to the covers or bindings of all classes of books, and the primary object is to provide a cover which may be hollow for reception of tensioning mechanism for the fthongs or equivalents on which the loose leaves are threaded, said cover comprising an outer frame presenting a smooth exterior wearing surface all round and one or more filling plates, boards or equivalents inserted in said cover in a plane normally below the frame so that the latter only receives the wear due to resting the cover on a desk or other surface whilst the filling does not come in contact with said surface; no other covering is thus necessary as is common in covers of the kind hitherto produced.

The invention consists in the novel constructions, arrangements and combinations of parts hereinafter fully described and specifically pointed out in the appended claims with reference to the accompanying drawings in which Figv 1 is a plan view of the upper cover of a loose leaf book of the thong type. Fig. 2 is an edge view. Fig. 3 isa section thereof on the line 33 of Fig. 1. Fig. 4 is an inside plan view of the lower cover of such a book and Fig. 5 is a section on the line 55 of Fig. 4. Fig. 6 is a vertical cross section of the cover shown in Figs. 1 to 3, taken on the line 6,6 of Fig. 1 and Fig. 7, is a similar view to Fig. 6 of a modification.

The covers are so formed or constructed as to dispense with a considerable portion of the binding hitherto generally used, that is to say, no exterior covering enclosing the framework of the cover is necessary. Such cover is constructed of an exterior framework a of suitable material such as fibre,

metal 51 wood into which is fitted one or more filling sheets or plates?) of metal, Wood, pasteboard, 'strawboard or the like the plane of said filling sheets being set I back or inwards from the outer plane of the frame. Aconvenient means for fitting the filling totlie framework is to provide the latter with one or more interior grooves or recesses 0 into which the edge or edges of the filling plates 6 engage or fit and in which they are secured by rivets or screws d or other appropriate fastening means or method. The filling plates or boards I) may be provided with outer coverings of any desired material to improve the appearance of the binder, but no covering to the frame is necessary as said frame will form the outer edge of the finished cover and take all the wear. Metal plates are preferred for the filling material since they counteract any tendency to warping of the material of which the outer framework is composed.

The aforesaid framework a may be formed of a single integral piece or of a number of members a a a a, in which case said members can be jointed or dovetailed at the corners as shown in Figs. 1 and 2, or at another part or parts and be secured in any appropriate manner as by screws or rivets c or by glue or the like; or again the framework may, with certain materials, be formed by bending the material to the desired shape and joining the ends. In any case and whatever method or material is employed the framework preferably presents a smooth unbroken line f f f for the whole outer length or contour of the cover, thereby forming the actual wearing surfaces of the cover and enhancing the appearance to a very great extent.

In cases Where two separated metal plates are employed as fillings for the exterior and interior of the cover respectively as shown in Figs. 3 and 5, the inner of said sheets may be in the same plane as the inner surface of the frame and the space between said plates may be used for accommodating tensioning mechanism for the sheets, not shown, or as shown in Fig. 7 where a solid cover is illustrated a single plate f may be inserted in the recesses 0, and attached to the frame by screws 7 to. produce arigid or solid filling.

In Figs. 4 and 5 the space 9 between the filling plates Z) may accommodate the usual lock and a slot is providediin one of the plates for sliding the locking mechanism commonly provided in this form of cover. Fig. 4 also indicates the thongs at h and in Figs. 1 to 5,- 11 designates clamping bars usable with these forms of cover.

The rear ends of the cover are soformed that they pass over the ends of the clamp ing bars as shown at a 'in Figs. 1 and 4 a hole being formed insaidcover ends and a corresponding hole in the ends ofthe. clamping bar. Through said holes is passed a partly threaded pin 7' forming a pivot or hinge between the clamping bar or cover, the unthreaded part of the pin permitting theicover to turn freely thereon.

'said framework being provided on its inner edge with recesses, spaced filling plates lodged in said recesses and firmly secured in said frame the outer one of said plates lying in a plane inwards of the eX- teri-or plane or surface of the frame.

In witness whereof I have signed this specification.

' ALBERT MANN.'
